This takes care of the (media content was not included due to a picture resolution or massage size restriction) error.
"if your jailbroken just use cydia" but this will still work. I'm using gevey sim no jailbreak
Make a backup of your iPhone in iTunes.

download ibackupbot
run ibackupbot and load the first backup you just created in iTunes.
go to com.apple.mms_override.plist
"library/preferences/com.apple.mms_override.plist"

I tried that but I cant find the cellular data setting so it didnt work

Are you unlocked with gevey? Tmo takes a little while to send(sometimes a loooong while). And sometimes you need to resend. So on your phone you go to settings/general/network/ there is no option for "Cellular Data Network"?
Can you make a backup of you phone now and check the new backup in ibackupbot to see if you have the proper code in the mms_override file?

change the string to wap.voicestream.com in ip3 only first.then restore and see if that helps.
<string>wap.cingular</string>

<string>wap.voicestream.com</string>

A few questions
1.have you restored and setup as new phone NOT from backup?
2.when you did the backup to fix the mms_override.plist did you have tmo service?was the phone connected to tmo when you backed up?
3.r u having issues with SMS,mms or both?
4.do you have data roaming on.is the E next to your carrier name in upper lift corner?

1. i think its back up
2. yes
3.both
4. yes

can i restore my phone and set up as a new phone still be able to unlock?

Well that's the first thing. I'm afraid you need to start with
1.restore as new phone
2. Get gevey going till tmo is working(you should now have network setting tab)
3. Backup
4. fix mms_override.plist,restore(make sure you use the backup you just made)restore(with ibackupbot)
Then we can narrow it down more.

Cannot send any sms or mms, I have gotten it to send both at one point, but then if the phone is turned off it stops working. I have looked with the ibackupbot and it seems to keep overwriting my changed, I will make the changed apply them, then on backup will show them, next time I power off the phone and back on all the old settings are back??? Any ideas? I cannot send any texts? thanks. I have done a reload setup as new phone twice, I can get it to work but then for now reason it will stop working, usually of the phone is ever turned off.

Well now, I just verified both files saved , still no texting, no sms or mms??
